The befriended animal would be empowered.
I think you would put me in that boat (although my approach is looser than what you describe).But there are people, plenty of them, who view HP as a metagame construct too. In spite of all evidence to the contrary (fungibility of HP via Vampiric Touch, the fact that contact poisons trigger on a "hit" and not on reaching 0 HP, the fact that HP function while you are asleep, etc., etc.) there are people who view HP degradation not as actual physical injury but rather as a kind of luck depletion
5e's resolution system is pretty open-ended. Your ability to train up an animal through 'mundane' means is limited only by your DM's judgement, in that sense. DMs are even encouraged to create new Backgrounds. 'Beast-tamer' or something could be one. Either way, your non-caster Ranger could have an animal. Not an Animal Companion in the in 3.x sense, but an animal they keep around.
D&D has often leaned towards the physically possible being inaccessible to fighters, but yeah, no reason anyone should need a ranger spell to have a pet. Even a dangerous wild one. Just, y'know, hope your DM finds the idea plausible, since he'll be setting the DCs.
5E begs for the DMs attention.
I'm not saying you're wrong, just that 5e does leave open having a non-spell-coerced/non-class-feature animal following your character around. Mind you, if the ranger does get a non-magical pet class feature at some point, it'll make it pretty unlikely that anyone without that feature will be able to talk their DM into a series of skill checks to 'tame' one. That's another issue that's just common to games like D&D, that expand by adding rules. Often a rule intended to introduce a new option will actually close that option off, by moving it from whatever open-ended sub-system it might have fallen under before, to a clear, defined sub-system.Yeah, "get your DM to buy your house rules" is just as BS as "hope your DM doesn't kill your pet" in my book. There's a difference between rules that are made to be flexible and adaptable to DM taste, and begging your DM to let something work.

FWIW.
